The book you are about to read is about research that asks questions like" How do our
senses operate?"" What is the connection between nervous system activity and perception?" …

This paper traces the history of the visual receptive field (RF) from Hartline to Hubel and
Wiesel. Hartline (1938, 1940) found that an isolated optic nerve fiber in the frog could be …

Does the world appear the same to everyone? Does what we know determine what we see?
Why do we see the world as we do? Vision is our most dominant sense. From the light that …

Theories of lightness, like theories of perception in general, can be categorized as high-
level, low-level, and mid-level. However, I will argue that in practice there are only two …

We reproduce suprathreshold perception phenomena, specifically visual illusions, by Wilson–
Cowan (WC)-type models of neuronal dynamics. Our findings show that the ability to …

Spatial filtering models are currently a widely accepted mechanistic account of human
lightness perception. Their popularity can be ascribed to two reasons: They correctly predict …

In order for an illusion to be so considered, two measurements are required. The most
common are the physical characteristics of the stimulus and some suitable index of its …

Geometrical optical illusions were given this title by Oppel in 1855. Variants on such small
distortions of visual space were illustrated thereafter, many of which bear the names of those …

The light reaching the eye from a surface does not indicate the black–gray–white shade of a
surface (called lightness) because the effects of illumination level are confounded with the …

Perceived brightness of a stimulus depends on the background against which the stimulus is
set, a phenomenon known as simultaneous contrast. For instance, the same gray stimulus …
